i BALLBEABING DOORFHANGER.

Specification of Letters Patent. Patented NOV, 26, 191%, A Application med May 21, lele; serial mi. 698,786. 'i

To all whom it mafyconcern:

Be it known that I, HARRY M. HA-UN, a

. citizenof the United States, residing at Ethanac.. in the county of Riverside, State of California, have invented .certain new and useful Improvements in Ball-Bearing 4of the same, such as willfenable others Skilled in the art to which it appertainsto make and use'the same, reference being had to the accompanying drawings, and to the characters of reference 'marked thereon, which forma part oft-his application.

. This invention relates to improvements inV sliding hangerddoors, -the objectof the invention beingV to produce a ball-bearing hanger for the door which will operate ina specially designed form of track way whereby'the door can'be moved along the track with easeV and precision and with a. minimum amount of friction and labor.

A further object of the invention is to produce a ball bearing hanger for the door wherein the door Awill operate inI a 4straight and true track which will render'the device capable of operating with a minimum amount of friction and which will reduce the necessityof replacing due tothe fact vthat there will be no swinging or vibration tive for the purposes for which iti's designed.

These objects, I accomplish by means of such structure and relative arrangement of `the partsas will fully appear by aperusalj ofthe following specification and claim.

On the: dra-wings similar j characters of reference indicate corresponding parts .in the sveral views.v y 'Figurel is a 'ront'elevation of a d oor showing the same inpositionwith my 1mprovedhanger and track "-connected therewith. Fig. 2 -is a sectional view taken on'a 4line X--X of Fig. 1. Figi?) is 'a sectional View o f'a detached portion of the track and fdoor taken on'a line Yf-Y- of Figg2. Fig.. 4 is a fragmentary part of a ldoor and hanger showing amoditied form of'hanger from'that shown in Fig. 3l Fig. 5 is a top .plan view of a circular track way adapted for use with a circular door as will appear. Referring now moreparticularlyto the characters of-reference on the drawings, the numeral 1 designates a building having the usual door opening adapted to be closed by a sliding door 2.

My invention embodies first a track mem- .ber consist-ing. of an upper inelosing member 4 p1 ided with aninner groove 5, such member L having projecting flanges V6 and 6@ bolted to which .are supporting bars 7 and 8,'such bars 7 being bolted to the building 1 in a perpendicularmanner Vand the bars 8 curving outwardly over the member 4 and being bolted to the members y7 land 41. Bolted to the member 6 is a flange 9 havin a curved portion 10 and bolted to the memlier 6a is a iangegll provided with a curved portion 12 spaced from the portion 10 to form a slot 13. f

The numeral 14 designates the hanger proper which will be provided with holes 15- to receive balls 16. These balls will fit snugly in the holes 15 and both the balls and the holes .will loev strictly smooth on their surfaces in order that there .may be a minimum Afriction between them. The balls 16 will fit .snugly into the curved surfaces ,of the members 10 and 12 and the hanger 14. will projectthrough the slot 13 and beconnected with the door -2 by means of vbolts or similar fastening structure.

In -practicethe bolts 11a which project through the member 11 and through. the member 6apass through Aelongated slots 11h in said ymember 1 1, wherebysuch member 11 will be adjusted to 4make the slotflS of 'just a sufficient width Ito receivethe hanger 14 suiiciently close to-preve1`1t vany vibration or swinging of such hanger' with the weightA of the door and to cause it to run ina true and accurate ,ma-nner. i This adjustment of course would only be used in case the parts became loose by reason of .wear on the balls or the runways. i

The Width of the hanger la is substantially aone-thdfotthe diameter of the balls 16' thus permitting vol'iefthird of the balls 16 to project on each side of the hanger 14 thus distributing the 4lOli-ng.of fthe balls!- equally between the hangerand th Vtracln` way to causathe track andfballs'ito'fmove easily and with a minimum amount of friction.

ith each end of the' track-Way, is a. small hole 17 through which may be projected pins ..18 to form a stop or closure at the end of .thevtraokfway to prevent the hangers from be provided with these holes 17 in order to cause no confusion 1n setting up the track, but the pins of course Would be only set thro-ugh the ends' of the installed track. I may have for some use a curved track-way 19 and a corresponding' curved door as shown in Fig. 5 in which event I would use a hanger 20 provided with a single ball 21,

the rest of the n structure being the'same as shown for the other views.

4Q f course the track-Way and the hangers and the balls Will be of any size desired or of any-materialdesired but preferably of such size and suchmaterial as Will make the 5: same as lightas possible and still be suHiciently strong and have but a minimum amountof friction between the parts;

-' The hangers 14 will of course project at a slight distance above the ball 16, in fact onlyk such a distance as Will supply the necessary strength for the device.

While this specification sets forth in detail the'present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as 'do not form a departure from the spirit of the invention.

Having thus described my invention What I claim as new and usefuland desire to secure by'Letters Patent is: A device of the character described comprising an upper inclosing'member provided with a groove in its under face, a projecting fiange on each sideof said member,'a track way comprising two curved members spaced apart and secured Ito said projecting flanges, hangers vprojecting between said curved members and provided with holes, balls mounted in said holes and bearing against said curved members, and a 'door swung on said hangers, as described.

ln testimony whereof I ailix my signature in presence of two Witnesses.
